EYEGLASS-FRAME.

Patented Nov. 1916.

Application filed April 17, 1916. Serial m. 91,515..

The object of my invention is to provide means whereby a set of 'lens-clampin' g bands may have their ends secured together indei C of the noseb'r-idge G,

pendently of the bridge connection and independently of the nose clamps, wherebythe nose clamps may be removed and replaced without disengaging or releasing'the lenses and whereby either lens may be released and removed without afiecting the nose clamps or their actuating springs.

In the drawings-Figure 1 is a front elevation, one of the sets of clamping lugs being illustratedin vertical section. 'Fig. 2 is a sectional View on line 22 of Fig. 1. .Fig.'

3 is a fragmentary view,showing the clamp ing lugs in vertical section and slightly separated. This view also embodies a slight modification of the interlocking means.

Like parts are identified by the same. reference characters throughout the severalviews.

Each of the lenses A is encircled by a clamping band or'strap'B, one end of which is permanently secured to the abutment lug while thexother end of the band is secured to a-lug D-adapted to fit against the end surface ofthe abutment C, the two members C and D constituting clamping lugs.

These lugs are preferably formed to interlock, a projection C" on the abutment lug 0 being adapted to engage in a corresponding recess in the margin of the lug D. Both of these lugs are centrally apertured to receive a connecting post E,

which is preferably rigidly secured to the.

abutment lug C. At its lower end, the post E is provided with a screw-threaded socket adapted to receivea clamping screw F, the head ,fi" of which bears against-the under surface of the lug D. I Y

Tiheupper end. of he post E is provided with a similarscrew G engaged in a thread ed socket in th'e upper end portion of the post, and havingahead Gr against which the actuating spring H of the nose guard I 18 adapted to bear. The nose guard or clamp Iis provided with a turning plated inter- Y posed between the lo'wer'end" of the spring Hand the lug or abutment" C, thespri'ng H. belng connected at h with the turningplate J. The post E passes-loosely through an thumb piece of ordinary construction wliere-' aperture in the plate J K is an operating; I

bythe nose clamp or'guard maybe actuated against the tension of the .spring H to re-' .65

leasing pos'ition. The upper extremity of the spring H is extended frombeneath the screw head G in"the'form of. an arm L whlch engages the clamping band B near its connection with abutmentlug' C, whereby the spring, is prevented from. unwinding.

. The lugD'loosely engages over a lower end of the post E and is held up against abutment lug Csolely by the head F of the; clamplng screw F. Therefore, when screw Y F is removed, the lug D maybeswung lug C, it is obvious that the nose guard I will not be aflected and that spring H will not be disturbed. This is an important fea-.

ture of my invention since the parts are ex tremely small and when the spring H is re 'leased,careful workis required to replace it.

under proper tension, It is also difficult, when replacing spring I-I,to hold it in poin capping relation to post E. 'Therefore,

with my improved construction, frequent.

'sition while the screw G is being replaced 7 tion. I also attach considerable imporf tance to the interlocking member C, since.

'this prevents any. oscillatory movement of the lug D upon the lug C. While I have described the screw F as'a clamping screw,

1 it is not essential to my invention that this screw should forcibly press the member D against member C. It will be sufiicient if the screw F holds the lug D in approximate contact with the lug C, since the interlocking projection C may be utilized to prevent movement.

In Fig. 3.I have illustrated"the band B and clamping lugs C and D in releasing position. This view is also slightly modified from the construction shown in Fig. 1, in

that the interlocking projection C" is formed on the lug D and is adapted to project into a recess in the lug C.

connected with one of said lugs, a spring ac:

tuated nose guard mounted upon one side of 'the lugs,.a projection on the opposite side of said lug, the other lug being socketed to receive said projection, and a clamping screw adapted to enter said pro ection and ar- Jranged to bind said lugs together.

3. The combination with a lens engaging strap provided at its respective ends with clamping lugs, a nose bridge permanently connected'with one of said lugs, a spring actuated nose guard mounted upon one side of the lugs, a projection on the opposite side of said lug, the other lug being socketed to receive said projection and a clamping screw adapted to enter said projection and arranged to bind said lugs together, saidlugs being formed to interlock with each other at one side of said projection.

4. eye-glass frame including the com bination with a nose engaging strap, of a pair of clamping lugs, each connected with one end of the strap, a post on one lug socketed in the other, a-clamping screw connected with said post and adapted to bind the lugs together and an interlocking member on one of the lugs, socketed in the opposing lug adjacent to said post and adapted to prevent pivotal oscillation of the lugs upon said post.

5. The combination with a lens engaging band or strap, of a pair of lenses each secured to one end of the strap, a post extending through one of the lugs and removably socketed in the other lug, a. clamping screw adapted to engage one end of said .post to bind said lugs together, a nose guard mount ed on the other end of said post, a removable post cap, and a spring interposed be tween the said cap and a portion of the nose guard, said spring having one end connect ed With the nose guard and the other end projected into engagement with the lens strap, said parts being organized to permit independent separation of the clamping-lugs or of the nose guard and spring substantially as described. 7

In testimony whereof I aflix my signature in the presence of two witnesses.
